Embodiment
See also its implementation process of description of drawings:
A kind of high-pressure vacuum breaker comprises operating mechanism, and operating mechanism case and drive disk assembly, described operating mechanism are permanent-magnet manipulating mechanism 4, and operating mechanism and drive disk assembly are positioned at the operating mechanism case; Described operating mechanism case is in the rectangular casing 9 transverse bottom plate 8 to be set, certainly casing 9 also can be other shape, and base plate 8 is fixed on the mounting panel 25, generally is to fix by screw, two mounting panels 25 are fixed on the casing 9, and permanent-magnet manipulating mechanism 4 is installed on the base plate 8 by screw.Three supports 10 are fixed on the base plate of casing 9, insulated tension pole connecting plate 11 1 ends are movably connected on the driving shaft 6 between support 10 biside plates, insulated tension pole 12 in the other end and the insulating cylinder 13 links to each other, driving shaft 6 links to each other with the insulated tension pole connecting plate 11 of three supports, 10 centres respectively, mechanism's pull bar 5 is connected on the moving iron core 18 of permanent-magnet manipulating mechanism, the other end of mechanism's pull bar 5 links to each other with connecting plate 7, and connecting plate 7 is connected on the driving shaft 6 again.When permanent-magnet manipulating mechanism 4 energisings or outage, moving iron core 18 side-to-side movements in the permanent-magnet manipulating mechanism 4, moving iron core 18 motions just drive mechanism's pull bar 5 motions of fixedlying connected with it, and 5 motions of mechanism's pull bar just drive connecting plate 7 motions.Because connecting plate 7 is connected with driving shaft 6, driving shaft 6 drives three insulated tension pole connecting plates 11 in the support 10 simultaneously, insulated tension pole 12 in insulated tension pole connecting plate 11 and the insulating cylinder 13 is connected, and insulated tension pole connecting plate 11 drives insulated tension poles 12 and moves up and down, the realization vacuum circuit-breaker deciliter.Separating brake handle 1 and 2 vertical linking to each other of separating brake connecting axle, the other end of separating brake connecting axle 2 is arranged on the bearing pedestal 16, bearing pedestal 16 is fixedly connected on the permanent-magnet manipulating mechanism 4, position near permanent-magnet manipulating mechanism 4 on the separating brake connecting axle 2 is provided with eccentric shaft, when eccentric shaft rotates to an angle, eccentric shaft is touched mutually with the loam cake 17 of permanent-magnet manipulating mechanism 4, in case of emergency, rotate separating brake handle 1, separating brake connecting axle 2 drives eccentric shaft and rotates under the rotation of separating brake handle 1, eccentric shaft drives manual brake separating roller 3 again.The manual brake separating roller 3 powerful driving shafts 6 that promote force breaker open operation under the effect of external force.At this moment, the external force effect has exceeded the sphere of action of magnetic force greater than the magnetic force of permanent-magnet manipulating mechanism 4, so make breaker open operation by force.Structure at described permanent-magnet manipulating mechanism 4 is, be provided with moving iron core 18, inner yoke 19, switching winding 22, magnet 20, closing coil 21 in the cavity that loam cake 17 and lower cover 23 and outer yoke 24 constitute, mechanism's pull bar 5 is fixedly connected on the moving iron core 18, bearing pedestal 16 is fixed on the loam cake 17, and separating brake connecting axle 2 is fixed on the bearing pedestal 16; Mounting panel 25 is welded on the casing 9.Moving iron core 18 links together with mechanism's pull bar 5, and after closing coil 21 energisings, closing coil 21 produces magnetic field moving iron core 18 is inhaled, and simultaneously, under the effect of inner yoke 19 and magnet 20, makes iron core 18 keep this state.When needing separating brake, give switching winding 22 energisings, switching winding 22 produces an opposing magnetic field, and iron core 18 is risen.
Those skilled in the art's simple replacement and change all are within the protection range of this patent in this area.
